Adapter XL710-Q2 available
How can i proceed
Thank you for posting in Wired Communities. I am not sure where you obtain the NIC but we do not support engineering sample. Our official firmware is not applicable for engineering sample as this kind of network adapters are manufactured prior production which are not the finalized version. Please contact your point of purchase to get a production Intel retail network adapter for the firmware update. You may refer to the valid part number of Intel retail network adapter in the following website:

Hope the above information help.
